Patent GB-150100-A (GB)
Abstract: 150,100. Keith, J., and Keith, G. June 10, 1919. Pilot jets.-The pilot-jet supply passage of a gas lamp having an automatic lighting-device, or a gas cock, is provided with a constricted part or injecter with a connexion to the main burner or burners so that, when the pilot-jet valve is closed and the main burners are alight, the gas issuing from the nipples of the burners sucks away any gas leaking past the pilot-jet valve and prevents it from passing to the pilot jet. In an automatic lighting-device substantially similar to that described in Specification 6395/15, [Class 135, Valves &c.], the gas supply to the pilot-jet tube passes through an injector A, removably fixed in the cover C of the diaphragm chamber and having a hole B in its side, communicating with a chamber between the cover C and the plate C' at the back of the diaphragm; the chamber communicating by way of a port D and a hollow jet-screw E with the pipe F, which supplies the enriching gas to a burner at the moment of ignition. The tube F is connected either to the side of the mixing-chamber of the burner or to an annular passage surrounding the nipple, and a spring S acts directly on the plate C'.

Title: Improvements in or relating to straight bar knitting machines
Inventor: WOODCOCK GEORGE SYDNEY
IPC: D04B11/00
Filed: 1964-04-11
Abstract: A straight-bar machine having the needles frictionally mounted in the needle bar so that needle selection can be achieved by maintaining selected needles depressed as described in Specification 1,001,591, has additional patterning mechanism whereby some of the needles normally retained in a lowered position are permitted to rise to tuck height so that what would presumably be long lengths of float yarn occurring in the fabric as the result of the depressed needles failing to take yarn are tucked and caught in with knitted loops of the fabric partway in their length.  As described in Specification 1,001,591 selected slides 17, Fig. 2, (not shown), are projected to engage above the corresponding needles of the machine and retain selected groups of them in a lowered position when the needle bar and remaining needles are raised.  The slides 17 are projected by a pattern drum 18 periodically rotated in either direction by pawl and ratchet mechanism operated from the main cam shaft.  In addition the pattern drum is mounted on a slide which is coupled by linkwork and operated from the main cam shaft to cause the drum to move into engagement with the slides and project the selected ones above the needles.  To avoid long floats of the yarns occurring in the fabric where a group of needles would normally be retained at a low level additional patterning mechanism is provided at the rear of the needles and comprises a pattern drum 34, Fig. 8, (not shown), having a series of projections 35, 36 disposed in a predetermined order. The drum 34 is mounted on a slide and is rotated by pawl and ratchet mechanism from the cam shaft of the machine and is also slidably operated by linkwork and cams on the cam shaft to cause the projectors 35, 36 to be periodically disposed above desired needles. These latter needles are selected to be disposed midway in a group of the normally depressed needles but the latter selected ones are permitted to rise and engage beneath the projections 35, 36.  They are thereby retained at tuck height and are caused to engage and tuck in that part of the yarn which forms the float and thereby prevent the occurrence of long unattached floats in the fabric.

The carriage 3 slides in a groove 2 on the base 1 and is provided with a rack 14 and a series of vertical slots 15 in a back plate 13. The base 1 is extended at 12 to support the shift and locking gear. A bolt 16 slides in a bracket 17 and is drawn into engagement with one of the slots 15 by a spring 19. A handle 20 serves to withdraw the bolt. The forward end of the bolt rests upon latch members 18 carried by arms 33 on the inner ends of two short shafts 27, 28 mounted in three brackets 30, 29, 30. Upon these shafts are also mounted the spring levers 24, 25 of the shift keys 22, 23, which levers engage the forked ends of arms 36, 37 pivoted at 38. Pivoted also on the same pivots 38 are pairs of bearing plates 42 carrying between each pair a toothed wheel 41 engaging the rack. Pawls 45 are pivoted to the levers 36, 37 and are slotted to engage pins 46 carried between the bearing-plates. When the bolt 16 is withdrawn, the carriage may be moved to any position. To move one step, say to the right, the key 22 is depressed and the shaft 27 rocked. The latch member 18 engages a bent over part 35 on the bolt and withdraws the latter. At the same time, the end of the spring lever 24 rocks the arm 36 and moves the pawl 39 up to engage the wheel 41. The slot 45 allows of lost motion so that the bolt 16 may be withdrawn before the carriage is moved. After the pawl engages the wheel 41 the latter is swung bodily to the right and moves the carriage through the space between two slots. The bolt 16 is released as soon as the latch 18 which is curved permits. The lever 24 is returned by its spring, the pawl being withdrawn and the wheel 41 rotating idly. Similar operation of key 23 moves the carriage to the left.

Abstract: 794,906. Flying spot particle counters. CAUSLEY, D. J., ROBERTS, F. F. W., and YOUNG, J. Z. May 20,1955 [May 27, 1954], No. 15762/54. Class 40 (3). Transparent or translucent particles are counted and/or sized by positioning or projecting them on to a field of view and causing one of two scanning beams, separated parallel to the scanning direction, to traverse a particle so that its phase is varied before the two beams are recombined and face on to a photo-cell, the output of which consequently varies with the phase difference between the beams before they are combined, this output being used to operate counting and/or sizing means. Apparatus for carrying out one form of the method comprises cathode-ray tube 1, Fig. 1, providing a flying spot beam 2 incident on a birefringent plate 3 forming beams 4, 5 separated in the scanning direction. These beams are focused at 6 on the specimen 7 and are then re-combined by birefringent plate 9 and passed through a “ plate 11 to a photo-cell 12. Due to phase variations introduced by the passage of a beam through a particle at 7, the two beams interfere and so produce a photo-cell output proportional to the phase difference between the beams after one thereof has passed through a particle. This output is applied via leads 15 and 18 to counting circuits as described for instance in Specification 739,902. In another form, Fig. 3 (not shown), the beam 2 is split by a half-silvered mirror or a glass plate, one split beam traverses the specimen and the other serves as a reference beam, the two beams subsequently being recombined so as to interfere and impinge on the photo-cell. The output from the photo-celL may also be applied to an integrator connected to a cathode-ray display tube producing an intensity image of the particle.
